HOB SEI-IOOF-TRIMMER Specification of Letters Patent.

Patented July 14, 1908.

Application filed November 7, 1907. Serial No. 401.177.

To all whom it may concern:

Be it known that I, WRIGHT MoGowEN, a citizen of United States, residingat Fanshawe, Oklahoma, have invented certain new and useful Improvementsin Horsehoof- Trimmers; 'and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention has relation to devices for trimming the hoofs of horsespreparatory to shoeing the same; and it is the object of the inventionto provide improvements whereby the trimming device may be held moresecurely on the hoof and the knife supported and operated with theutmost advantage.

The drawings hereto annexed and forming a part of this specificationillustrate in Figure 1 a plan of the invention. Fig. 2 a like viewshowing the knife in a different position. Fig. 3 a section on the line3 3 of Fig. 1. Fig. 4 is a transverse section on the line 4 4. ofFig. 1. Fig. 5 is a side elevation.

Similar characters of reference designate similar parts or features, asthe case may be, wherever they occur.

In the drawings 1 designates the hoof clamp which is composed of a bowedstrip of resilient steel or similar substance, shaped in general to fitthe outside lower margin of the hoof of a horse or mule. The ends 2, ofthe clamp-strip are extended convergently to form a handle, when theyare brought nearly together to clamp the strip on the hoof. The saidends are also provided with a keeper which may be slipped up thereon soas to maintain the clamp on the hoof automaticallv.

The clamp strip is provided with a transverse bar 3, the ends of whichare tenoned and projected through slots 4 in the sides of the clamp atthe base of the heel forming a shoulder at the inner ends of saidtenons, so that a limit is formed to the extent of which the clamp maybe pinched around the hoof. From the tenon into said cross-piece 3 is apiece 5 extending from the cross-piece forwardly to near the middle ofthe hoof on the end of which forwardly projecting piece 5 a knife 6 ispivoted by means of a bolt secured in the piece 5, said bolt projectingfrom the hole in the knife and secured in place by a cotter pin 7. Thisafiords a means for swinging the knife around from the extremest pointsto which it may be desired to operate it. The handle of the knife isturned upward at the outer end so as to facilitate the manner of takinghold of it and operating it without danger of injuring the fingers. Theforward end of the knife is curved upwardly and ointed as shown so as toafford means by which the hoof may be cleaned preparatory to having theclamp placed thereon and the hoof trimmed. The knife is two-edged, asshown, so that the trimming of the hoof can be effected from the rear orthe front.

In case of necessity of grinding the knife it can be easily removed bytaking out the cotter pin 7 in the plate 6 and after the knife shallhave been sharpened it can be replaced instantly.

By providing a steel spring clamp as stated, formed in one piece thehoof can be grasped quite tightly by squeezing the-ends of the clamptogether and be held and moved about by one hand holding on to said endsand the other left free to operate the knife as may be desired.

It is recognized that it is common in the art to employ clamps andknives operating upon a pivot placed on some means connected with theclamp, the clamp itself being composed of iron or other means lessefficient than the resilient strip of steel shown for the purpose forwhich it is provided.

That is claimed is 1. A hooftrimmer composed of a strip of resilientsteel bent into bowed form approaching the shape of the outside lowermargin of the hoof of a horse, the ends of the bowed strip beingextended and bent inward convergently to form a handle whereby thesqueezing together of the extended ends may tighten the clamp on thehoof, slots formed in the sides of the clamp near the heel, a cross-barprovided at its ends with tenons extended through said slots, a bartenoned at its rear end in said cross-bar and extended forwardtherefrom, and a knife pivoted on the inner end of the said latter bar.

2. A hooftrimmer comprising a clamp composed of a single strip ofresilient steel bent to a form approaching the shape of the outsidelower margin of the hoof and having In testimony whereof, I affix mysignature, gxterlllded enls thit rilsqil be squeezed togetlilier inpresence of two witnesses.
